Why I wrote this
I started working in this trade at 14 years old. I'm the owner of Go With The Flow now, and I've spent more than three decades around grease traps, commercial lines, vacuum trucks, small businesses, large facilities, and every kind of customer across NW Indiana and the south side of Chicago.
Most of what I'm about to share I had to learn the hard way. None of it is in a textbook. I'm putting it here because I'd rather you know it than have someone take advantage of you because you don't.
Tip 1 — The cheapest sewer call is the one you scheduled
An emergency call after hours costs roughly 2 to 3 times what the same job costs during normal hours. If you have *any* warning sign — slow floor drain, grease smell, trap overflowing, water coming up, line backing up — call during business hours. That single habit can save a small business thousands over time.
Tip 2 — Know what problem you are actually paying to solve
If the problem is grease, pumping and cleaning may solve it. If the problem is a collapsed or broken line, pumping alone will not. If the same issue keeps coming back, ask for proof: photos, manifests, camera footage, or a clear explanation. You should understand what you are paying for before anyone starts.
Tip 3 — "Free" is rarely free
"Free estimate," "free camera with service," "free second opinion." These are fine if the company is reputable. They're a warning sign if the company then quotes you 3x the going rate and pressures you to sign today. Free that comes with high-pressure sales isn't free — it's bait. Get a second quote. Always.
Tip 4 — The same backup twice is a diagnosis
If you have the same line or trap problem twice in the same year, stop treating it like a surprise. It may be a schedule problem, a grease buildup problem, a solids problem, or a structural issue. Three emergency calls cost more than one proper maintenance plan.
Tip 5 — Chemicals are never the answer
I will not name brands, but: every drain opener on the shelf at the hardware store is bad for your pipes, bad for the next person who has to open that line, and ineffective on anything beyond a hair clog at the trap. The marketing is great. The chemistry is awful for older homes especially. Skip them.
Tip 6 — Trust the company that explains things
If the technician hands you the camera screen, points at the spot, and says "see that ring of grease around the pipe wall? That's why you're calling us every three months" — that's a company that wants you to need them less. If they say "yeah it's pretty bad in there, gonna need a big job" and won't show you anything, that's a company that wants you to need them more. The difference is night and day.
Tip 7 — Get the scope in writing
Know what is included before the truck starts: pump-out only, scrape and rinse, jetting, camera, disposal, manifest, after-hours rate, return visit, or minimum charge. If it matters, it should be written on the invoice or quote.
Tip 8 — The grease trap rules ARE enforced
Restaurant owners: the 25% rule (pump when FOG hits 25% of trap volume) is not a suggestion. The health inspector and the municipal sewer authority both check. Fines are real. They go up fast on repeat violations. And a backed-up trap during the dinner rush can close you for the night. Get on a schedule. Keep the manifests in a folder.
Tip 9 — Commercial kitchens need a real schedule
Some businesses need monthly grease service. Some can go quarterly. Some need extra service before holidays, festivals, school seasons, or big catering weeks. The schedule should match your actual volume — not a guess, not whatever the last tenant did.
Tip 10 — Tip from my dad, who taught me this trade
"If you treat every job like the customer is your grandmother, you'll never run out of work." I've never seen a better business plan than that. We try to live by it. When you call us, that's the standard.
What I wish every customer knew before calling anyone
- Get the price range on the phone. A reputable company can quote a range over the phone for almost any standard service.
- Ask for the technician's name. Ask if they're an employee or a subcontractor.
- Ask for proof of insurance. It should be available for commercial accounts.
- Ask if there's an after-hours rate and what it is. Get a number, not "depends."
- Read one Google review and one BBB complaint before you book. Both. Five-star reviews only mean the good days; one bad complaint tells you how they handle the bad days.
Final thought
There are great companies in this trade and there are companies that survive on people not knowing any better. You being here, reading this, already puts you ahead of most customers. Use it.
Call us if you want, hire someone else if you want — but don't hire anyone who can't answer the questions above.
